Application filed September 28, 1921. Serial No. 503,942.

To all whom it mayconcern.

Be it known that I, WALTER E. Almanac, a citizen of the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented new and useful I mprovements in Printing Presses, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification. I

My invention relates to printing presses and particularly that type of press which comprises a sheet delivery mechanism and a receiving table whereby the sheets or art1 cles may be continuously and automatlcally delivered from the press proper to the receiving table.

In printing presses of a form 1n general use, the ink fountain is disposed under the surface of the press bed and intermediaIte n this position, the'ink fountain is inaccessible during the operation of the printing press unless provision is otherwise made to render the ink fountain available to the workmen or attendants for adjusting it. There are other objections to such an arrangement in a printing press. To overcome these ob ections, it has heretofore been proposed to provide a permanent open space between the receiving table and the press proper permitting access to the ink fountain by properly placing and designing a suitable sheet delivery mechanism thereby providing for this permanent separation of the press proper from the receiving table. This arrangement is, of course, objectionable because of the excessive floor space permanently required at the instance of the open space between the press proper and the receiving table which space is permanently open in order that workmen may, at infrequent times, have access to the ink fountain and the other adjusting mechanism.

By means of my present invention, the aforementioned objection is overcome by eliminating the permanent open space or passageway between the press proper and the receiving table. At the same time, the attendant may have ready access to the ink fountain when desired, and all of the other advantages obtain in my present printing press which accrue by reason of the above mentioned permanent separation of the press proper from the receiving table.

A further object of my invention is to provide a printing press in which the receiving table is normally abutting the press proper in order to occupy minimum floor space, but which is capable of being moved at will to provide an open passageway there between and the press proper so as to permit of ready access to the ink fountain and the making of other adjustments. Also, the operation of my press neednot be discontinued while the receiving table and ress proper are thus temporarily separated, masmuch as my delivery mechanism is extensible and contractible to permit of continuous operation for delivering from the press proper to the receiving table irrespective of the position of the receiving table with respect to the press proper.

Another object of my present invention is to provide a printing press of the character indicated above in which the height of the receiving table may be automatically varied irrespective of its position relative to the press proper.

Another object of my invention is to provide a printing press of the above mentioned type, in which the sheet delivery mechanism may operate continuously irrespective of the location of the multi-positionable receiving table and be automatically timed so as to regularly deliver the articles or sheets to the receiving table without interruption, in spite of the varying times of delivery to which the sheets or articles are subjected by reason of the variable span of the delivery mechanism over the space'between the press proper and the multi-positionable receiving table.

With these objects in View, my present invention consists in certain features of novelty in the construction, combination and arrangement of parts by means of which the aforesaid objects and other objects to be hereinafter described may be attained.

For a better understanding of the nature, the scope and the characteristic features of my invention, reference may be had to the following description and the accompanying drawings, in which- Figure 1 is a view in elevation and somewhat diagrammatic of a portion of a printing press embodying a form of my invention;

Fig. 2 is a plan View of the printing press structure shown in Fig. 1;

Fig. 4 is a view similar to Fig. 3 in which the carrier of Fig. 3 is extended to its outermost position when the receiving table abuts the press proper;

Fig. 5 is a View showing my delivery mechanism when the receiving table occupies a position remote from the press proper and wherein the carrier of the delivery mechanism occupies a position similar to that shown in Fig. 3;

Fig. 6 is a view showing my delivery mechanism when the carrier occupies a position similar to that shown in Fig. 4 and the receiving table occupies the position shown in Fig. 5; and

Fig. 7 is an enlarged View showing a portion of the printing press of Fig. 1 whereto mechanism is attached for automatically varying the height of the receiving surface of the receiving table.

The printing press of my invention comprises a press proper 1; a receiving table 2 and a delivery mechanism 3. The printing press proper is of a well known form of construction comprising, among the usual features, an ink fountain 4 which is arranged at one end of the bed of the press proper and placed intermediate thereb-e tween and the receiving table 2. The'ink fountain 4 is supported u on a main frame 5 of the press proper an at the opposite end of which, is mounted an adjustable impression cylinder 6. The press proper herein illustrated is of a common commercial type such as is illustrated in U. S. Patent, No. 909,199.

The frame 5 is provided with two spaced longitudinally extending horizontal arms 7 and 8 which are respectively supported at their outer ends by means of post members 9 and 10. The horizontal portion of each of the arms 7 and 8 is provided with two spaced longitudinal slots 12 and 13. The re ceiving table 2 is disposed intermediate the arms 7 and 8 and is suspended therefrom by means of laterally extending lugs 14 and 15 that are rigidly secured to the receiving table 2 and received respectively in the slots 12 and 13. The lugs 14 and 15 slidingly engage in the slots 12 and 13 and permit of the receiving table 2 being moved longitudinally of the press proper 1. Thus, it will be observed that the receiving table 2 is multi-positionable with respect to the press proper 1, but normally occupies the position shown in Figs. 1 and 2, wherein the receiving table abuts the press proper 1. In this position there is no open space to permit access to the ink fountain 4, inasmuch as the receiving table 2 is placed closely adjacent to ing an open space adjacent to the ink fountam 4.

The delivery mechanism in my printing press comprises automatically adjustable means for delivering the sheets or articles from the press proper 1 to the receiving table 2. Inasmuch as the receivin table 2 is longitudinally adjustable of the press pro 1r 1 it is necessary, in order to provide for the variable span between the receiving table 2 and the press proper 1, that the delivery mechanism 3 be extensible and contractible to correspond with the various positions that the receiving table 2 may occupy with respect to the press proper 1 so that the printing press may be continuously operable irrespective of the proximity of the receiving table 2 to the press pro er 1.

The extensible and contractib e delivery mechanism 3 that I employ in conjunction with the variable positionable receiving table 2 comprises a tape delivery mechanism 16 and a carrier mechanism 17 which, in this instance, is shown as being a reciprocating carrier having a uniform stroke, although it will be obvious to those skilled in the art that a carrier of other forms may be used, such as are illustrated in U. S. Patent, No. 610,491. By the term carrier, I refer herein to a fly carrier which operates either as a reciprocating device or as an oscillating device, as well as other forms of carriers that are well known in the art and illustrated, for instance, in the aforesaid patent.

The tape delivery mechanism 16, as shown in Figs. 1 and 2, comprises a plurality of spaced endless conveying tapes 18 that extend longitudinally of the press and are severally supported at one end of the delivery mechanism by spaced supporting members or pulleys 19 that are rotatably mounted in a cylinder-head 20. The tape delivery mechanism 16 is also supported by means of a plurality of groups of pulleys that are mounted on an upper framework which is supported on the frame 5 of the bed of the press proper. This framework comprises two spaced vertical columns 21, each of which is provided with a horizontal and longitudinally extending arm 22. At the upper ends of the columns 21, a transverse and horizontal shaft 23 is supported, upon which are mounted a plurality of spaced rotatable pulleys 24 that are severally aligned with correspondingly positioned pulleys 19. A plurality of rotatable pulleys 25 are likewise mounted upon a transverse shaft 26 which is j ournaled in downwardly extending portions, 27 that are formed on the outer extremities of the horizontal arms 22, as shown best in Figs. and 6. The pulleys are also aligned with the corresponding pulleys on the receiving table 2 are thus adjustable longitudinally of the press proper 1, as well as of the stationary pulleys 19 and 25. The pulleys 29 are likewise aligned with corresponding pulleys 19, 24 and 25. A plurality of spaced rotatable pulleys 31 are mounted upon a transverse shaft 32 which slidingly engages longitudinally extending slots 33 that are formed in the arms 22. The group of pulleys 31 is, therefore, longitudinally adjustable of the press proper, and the stationary pulleys 19 and 25. The pulleys 31 are aligned with the corresponding pulleys 19, 24, 28 and 25 comprised in'the tape delivery mechanism.

By referring to Figs. 2 to 6 inclusive, it will be noted that each of the several delivery tapes 18 comprises an endless belt, each traveling over one of the pulleys 19 disposed at one end of the tape delivery mechanism 16 and is engaged, in turn, by oneof the aligned pulleys 24, one of the pulleys 28, one of the pulleys 31 and one of the pulleys 25. The tapes 18 may be made of any suitable material which is flexible and substantially non-elastic. As the group of pulleys 28 is adjusted longitudinally of the press proper 1 and of the stationary pulleys 19, by reason of the group 28 being mounted upon the receiving table 2, the span of the tape delivery mechanism 16 must likewise be made extensible and contractible, and this is accomplished by the sliding pulleys 31. The sliding pulleys 31, as hereinbefore mentioned, are rotatably mounted upon a shaft 32, the outwardly projecting ends 35 of which'are embraced by cords 36 that extend over stationary rotatable pulleys 37 mounted on the framework adjacent to the pulleys 24. The lower ends of the cords 36 are severally provided with attached weights 38, as shown in Fig, 1. The weights 38 are received in the posts 21 of the frame '5, and by gravity action they continuously pull on the shaft 32, thereby tending to hold the pulleys 31 adjacent to the posts 21. However, the weights 38 are so balanced that when the pulleys 31 are moved away from the columns 21, the pulleys 31 will remain in their preselected position and they will be held stationary in such position byreason of the counterbalancing action resulting from the weights 38 and the counterpull exerted by the taut tapes 18. In other words, the tape delivery mechanism 16 is extensible and contractible, at

will, as the pulleys 28 are moved to various positions corresponding to the positions of the receiving table 2. While the tapes 18 are, of themselves inelastic, the tape delivery mechanism is extensible and contractible by reason of the automatic adjustment of. the pulleys 31 which are moved towards and away from the pulleys 28 as the receiving table 2 is adjusted longitudinally of the press proper 1. The action of the weights 38 eliminates all slack in the tapes 18. The tape delivery mechanism 16 is, therefore, extensible and contractible to span the variable open space between the receiving table 2 and the press proper 1.

The pulleys 19 are'rotated through a gear drive 19 mounted on the cylinder-head 20, as shown in Fig. 1,. and which is usual in cylinder-head printing presses comprising tape delivery mechanism.

In conjunction with the tape delivery mechanism 16, hereinbefore described, there is the carrier delivery mechanism 17 which, in this instance, and for the purpose of illustration only, is shown as a reciprocating carrier having a uniform stroke, althou h such a carrier is capable of having its stro e adjusted when the'printing pressis not operating. The reciprocating carrier 17 comprises a transverse bar 39 from which a plurality of longitudinally extending fingers 40 project. The fingers 40 are spaced intermediate the tapes 18, as shown in Fig. 2. When the receiving table 2 is in the position shown in Figs. 1 and 2, the reciprocating carrier 17 with its attached fingers 40 is located as shown when beginning a reciprocating stroke. delivered on the tapes 18 are brought in contact with the fingers 40 which in, turn, deposit the articles or sheets upon a receivin surface 41 which is comprised in the receiving table 2. This action'is similar to the reciprocating carriers shown and described in the aforementioned patents. Reciprocating motion is imparted to the carrier 17 through the agency of a double rack and pinion mechanism mounted on each side of the carrier 17 and each comprising an upper reciprocatory rack 42, a stationary lower rack 43, attached to the frame 30, and a traveling pinion 44. The racks 43 are secured to the sides of the frame 30 formed on the receiving table 2 and, as a consequence, are moved longitudinally of the press proper 1 as the position oft-he table 2 is varie d. The rotatable pinion 44 operably connects the lower rack 43 with the upper rack 42 and travels simultaneously over both of said racks. -The pinion 44 is journaled in the outer end of a crank shaft member 45, the 1 otherend of which is pivotally secured at 46 to a second rotatable crank shaft member 47, to which rotary motion is imparted through the agency of a mitered gear con- At this time the sheets or articles nection 48 that comprises a driving beveled gear 49 and adriven' beveled gear 50, the axes of said gears 49 and being disposed at right angles to each other. The crank shaft 47 being rigidly secured to the gear 50, is rotated in unison therewith and, consequent-1y, the crank shaft 45 is oscillated to and fro thereby causing the traveling pinion 44 to travel over the stationary rack 43 which, in turn, reciprocates the reciprocating rack 42.

In Fig. 3 the receiving table 2 occupies its innermost position and the rack 42 is likewise shown as occupying approximately its innermost position atone end of its path of travel.

In Fig. 4 the rack 42 is shown as occupying approximately its outermost position at the other end of its path of travel. In this instance, it will be observed that the crank shaft mechanism is extended and that the traveling pinion 44 has reached the end of its travel outwardly from the mitered gear connection 48. As the crank shaft 47 is rotated counter-clockwise from its position in Fig. 4, the travelingpinion 44 will move inwardly on the stationary rack 43 and return the reciprocating carrier-42 to the position of Fig. 3. From the foregoing, it will be observed how the reciprocating action is imparted to the carrier 17 in conjunction with the fingers 40 which are secured to the reciprocating racks 42 disposed on each side of the receiving table 2.

When the receiving table 2 is 'moved longitudinally of the press proper 1 to occupy the position shown in Figs. 5 and 6, it will be observed that the tape delivery mechanism 16 has been extended inorderto span the intervening space between the receiving table 2 and the press proper 1. As hereinbefore described, this extension of the tape delivery mechanism 16 is effected through the sliding action of the pulleys 31 which permit the several tapes 18 to be extended longitudinally even though the tapes 18 are, of themselves, inextensive.

I The mitered gear drive 48 is mounted upon a bracket 51 attached to the receiving table 2 and the relative positions of the mitered gear drive 48, the racks 42 and 43 and the traveling pinion 44'remain unchanged irrespective of the position of the receiving table 2, as shown in Figs. 5 and 6. The reciprocating carrier 17 is operated in the same manner as hereinbefore explained, When the receiving table 2 is remote from the press proper 1 as when immediately adjacent thereto.

In order that the mitered gear drive '48 ma drive the reci rocatin carrier 17 ir-' respective of the longitudinal adjustment of the receiving table 2, a driving shaft 52 outer end the beveled gears 49. The shaft 52 is journaled in the bracket 51 and extends longitudinally of the printing press. At its end opposite to the gear 49 the shaft 52 is provided with a longitudinally extending helical key-way 53. A beveled gear 54 supported in a bracket 55 in which theshaft 52 is also journaled is splined to the shaft 52 through the key-way 53. As the bracket 51 is moved in unison with the receiving table and is keyed to a'shaft 59 that is rotated by means of a mitered gear drive 60. Any suitable driving means may be utilized for driving the gear connection 60.

From the foregoing, it will be observed that the power furnished through the agency of the gear drive 60 is utilized in furnishing reciprocating movement to the carrier 17, irrespective of .the position that said carrier may occupy longitudinally of the press proper 1.

As hereinbefore mentioned, the reciprocatingcarrier 17 is described as possessing a uniform stroke. It is, of course, evident that when the reciprocating carrier 17 oocupies its innermost positionand is just ready to begin its reciprocating stroke in the direction of the receiving table 2, the sheets or articles to be delivered to the carrier 17 by means of the tape delivery mechanism 16 must be in such position that they may be received on the fingers 40 which are comprised in the carrier 17 and this action must uniformly obtain irrespective of the position of the receiving table 2. This results from the fact that the time of delivery between the printing press proper 1 and the reciprocating carrier 17, throiigh the agency of the tape delivery -mechanism 16, varies in accordance with the distance of the receiving table 2 from the press proper 1. This variable time of delivery must be properly compensated for in order that the reciprocating carrier 17 or articles traveling in unison with the tapes is provided upon which is mounted at its 18, are in a proper position so that the reciprocating carrier 17 may have full possession of them to ensure against their being displaced on the receiving table 2. To effect the proper timing between the tape delivery mechanism 16 and the reciprocating carrier 17 the key-way 53 formed 1n theend of the shaft 52 is so designed that the action of the crank shaft mechanism operating the re ciprocating member 17 is accelerated or re tarded, as the case may be, to effect proper delivery of the articles from the tape delivery mechanism 16 to the reciprocating carrier 17.

In order to effect automatic adjustment of the receiving surface 41 of thereceiving table 2, the mechanism of Fig. 7 is provided. The receiving surface 41 is supported on opposite sides by vertical screws 61 and 62 that are journaled in the frame of the receiving table 2 and threaded through'laterally extending lugs 63 formed on the receiving surface 41. As the screws 61 and 62 are rotated, the receiving surface 41 is raised or lowered accordingly. To im art rotative movement to the screws 61 an 62 the following mechanism is designed.v

A transverse counter-shaft 64 isjournaled in the brackets 51 and out of the path of travel of the rotating crank shaft member 47, the ends of the counter-shaft 64 being provided with sprocket wheels 65 which are connected respectively by chain drives 66 with sprocket wheels 67 that are mounted on stud shafts 68. The shafts 68 are journaled in lugs 69 which are formed on opposite sides of the frame of the receiving table 2. The upper ends of the screws 61 and 62 are connected through mitered gears 60 to the stud shafts 68 and the screws 61 and 62 are thus driven in unison by, reason of the power transmitted through the sprocket wheels 67. The shaft 64 is automatically rotated through any suitable connection by the reciprocating carrier 17 and in this instance, through the agency of the racks 42 to which a removable pawl 71 is pivotally secured, said pawl 71 being arranged to engage a removable ratchet wheel 72 keyed to the transverse counter-shaft 64. Each time the rack 42 makes a backward movement, the pawl 71 imparts a rotative movement to the ratchet wheel 72 that, in turn, rotates the screws 61 and 62 a suflicient distance to automatically lower the receiving surface 41 approximately a distance equal to the thickness of a single sheet of paper or the thickness of the articles to be delivered at one time. To automatically raise the receiving surface 41, the awl 71 is reversed as well as the ratchet wlieel 72. In these positions, the pawl 71 and ratchet wheel 72 will en-. gage with each other when the rack 42 makes a forward. movement.
